Melanie: *(murmuring to herself, scrolling through photos)* "So viele schöne Aufnahmen... und doch fühlt sich alles falsch an." Hunter: "Excuse me, miss. Mind if I sit? I'm Detective Hunter, Alborn PD. I just have a few questions about something that happened in town last night." Melanie: *(startled, looking up)* "Oh—entschuldigen Sie, ich habe Sie nicht kommen sehen. Sie sind von der Polizei?" Hunter: "...I'll take that as a yes. So, last night—around the old mill on Cedar Street. Did you see anything unusual? Anyone acting strange?" Melanie: *(eyes widening, voice trembling)* "Die alte Mühle... ja. Ich war dort. Ich habe Fotos gemacht, vom Sonnenuntergang, und dann—dann habe ich etwas gesehen. Eine Gestalt. Sie ist einfach... verschwunden." Hunter: "Whoa, hey, slow down. I'm not following any of that. You're saying... you were there? At the mill?" *(gesturing)* "Mill. You. Photos?" Melanie: *(nodding rapidly, fumbling with the camera)* "Ja, ja! Hier, sehen Sie. Ich zeige es Ihnen. Dieses Bild—da, im Hintergrund. Sehen Sie die Person? Und im nächsten Moment war sie weg. Spurlos verschwunden!" Hunter: *(leaning in, squinting at the screen)* "Okay, that's... a picture of the mill, alright. Is that—is there someone in the background there? Can you—can you zoom in on that?" Melanie: "Sie verstehen mich nicht, oder? Mein Englisch ist... ich kann kein Englisch. Aber das hier ist wichtig. Bitte, Sie müssen das ernst nehmen!" Hunter: *(rubbing his temple)* "Yeah. No English. Great. Look, I really need to know what you saw. This is the third disappearance this month and you might be the only witness." Melanie: *(growing more agitated)* "Drei? Es waren mehr als einer? Mein Gott... ich wusste, dass etwas nicht stimmt in dieser Stadt. Diese Ruhe, dieses Lächeln von allen—es ist alles falsch." Hunter: "Hey, hey. Easy. You're shaking." *(softening)* "Look, I don't know what you're saying, but I can tell you're scared. Whatever you saw, it's got you rattled. That tells me plenty." Melanie: *(quietly, clutching the camera to her chest)* "Ich habe Angst. Ich bin allein hier, in einem fremden Land, und ich weiß nicht, wem ich trauen kann." Hunter: "I'm gonna get someone who can translate, alright? Just—stay put. Don't go back to that mill. You understand 'mill'? Bad. No mill." *(shaking his head)* "God, I sound ridiculous." Melanie: *(a faint, nervous laugh)* "Mühle. Ja. Schlecht. Das verstehe ich." *(pointing at the camera)* "Aber die Fotos—nehmen Sie die Fotos." Hunter: *(his phone buzzes; he glances at it)* "Hold that thought." *(answering)* "Hunter. ...What? Where? ...No, I'm on my way. Don't let anyone touch the scene." *(standing abruptly)* "I have to go. Listen—" *(pointing firmly at her, then at the table)* "Stay. Here. I'll be back. Stay." Melanie: *(reaching toward him)* "Warten Sie! Die Fotos! Sie müssen sich die Fotos ansehen—bitte!" Hunter: *(already walking away, calling over his shoulder)* "I'll send someone, I promise! Just don't leave!" Melanie: *(alone again, staring down at the image on her camera, whispering)* "...Niemand hört mir zu."
